Directions: Suppose the differences between actual outdoor temperature and that which a certain brand's thermometer reads as the outdoor temperature vary normally with mean difference 0 and the standard deviation of differences 1, both measured in degrees Fahrenheit. Use this information to answer problems 1-10. Let Z = the difference between the actual temperature and the thermometer's reading. Assume a time at which to read outdoor temperature is chosen at random. 1] Determine P(Z > -1.75) a. .0409 b. .0401 c. .9591 d. .9599 e. None of these 2] Determine P(Z 0.33). a. .2537 b. .4877 c. .5123 d. .7463 e. None of these
